We thank the fishermen who collected the scales and phenotypic information and the people who organized and read the scales, in particular J. Kuusela and J. Haantie, as well as J.-P. Pohjola for reading the sonar data and M Länsman for compiling detailed river catch and effort data. A. Holmberg and NA Holmberg are thanked for sharing their extensive knowledge of traditional Sami fishing practices. We also thank E. Eriksen for providing corrected data on krill biomass and Ø. Langangen for sharing codes and information on the Gompertz multi-species model. Four anonymous reviewers are thanked for their constructive comments on earlier versions.
